Sorry for the confusion. I learn to use bufferevent by checking code of libevent1.4.8/test/regress.c which has the error cb defined as: static void errorcb(struct bufferevent *bev, short what, void *arg) That is where the 'what' (for my case I believe 0x21 is EVBUFFER_ERROR| EVBUFFER_READ) came from. Anyway, I won't use bufferevent for listen fd later. Thank you. Arthur
